IMPROVEMENT IN DUMPINGfWAGONS.

Specification forming part of Letters Patent No. 122,565, dated January9, 1872.

Be it known that I, WALTER W. CARR, of the city of New Orleans and Stateof Louisiana, have invented an Improved Dumping-Wagon; and I do herebydeclare the following to be a full, clear, and exact descriptionthereof, which will enable others skilled in the art to which it relatesto make and use the same, reference being had to the accompanyingdrawing forming a part of this specification.

This invention relates to that class of wagons which are designed tobeused almost exclusively for the purpose of dumping lumber and timber;and for such purpose it possesses a combination and arrangement ofcertain mechanical devices hereinafter particularly described, whichshall most eft'ectuall y accomplish the end in view. It is of simple andeconomical construction, While, at the same time, it possesses strengthand durability to a degree equal to that of any similar class of wagonsintended for the purposes to which this relates.

But my improvement will be more clearly understood -and appreciated byreferring to the drawing, which amply illustrates all that I claim asappert-aining to my invention, and whereon the similar letters refer tothe similar parts thereof, and on which- Figure l is a side view of myimproved wagon, with portions of the wheels thereof broken away, themore clearly to expose to View the particular parts which I claim as newand as pertaining to my device. Fig. 2 is a top view of my wagon ascomplete and ready for use.

Aarethe wheels, B,the axle; C, thetongue, all of which may beconstructed in the usual mannen D are adjustable side frames, withstirrups E attached to the rear part thereof, through which the forwardpart slides. These parts are, furthermore, secured together whenproperly adjusted to the desired length by pins al a. a a, or theirequivalents. The rear or lower part of this frame is, moreover,strengthened by a cross-plank, F, bolted or otherwise properly securedto its lower side and by the rear axle, to which, also, it is rigidlyattached by means of the stirrup G, partly visible on the drawing. Theforward parts of the aforesaid side frames D are iirmly held together bymeans of the bolster H, to which they are also rigidly attached bystirrups I, and by the connectin g-rod K running through the hollowcylinder L, which latter rotates loosely and freely thereon. The saidhollow cylinder, in connection With the bolster H, is designed tosubserve the purpose of furnishing a bearing for forward part of thelumber or timber thereon placed when relieved from the said bolster' H,and to further assist, by its free rotary motion, the operation ofthrowing the load to the rear while in the act of discharging it, ashereinafter described. M is a wooden or metal roller, of any properdiameter, through the longitudinal center of which passes a metal axle,having its bearings upon the rear part of the aforesaid side fra-mes D,and upon one end of which are placed a ratchet-wheel, N, pawl O, andlever P, by means of which a rotary motion is imparted to the saidroller M, and the lumber or timber for the rear part of which the saidroller M furnishes a bearing, is, by the driver, easily thrown to therear of the Wagon or truck, with the hind end thereof upon and in directcontact with the ground. The forward movement of the draft animalsattached to the wagon will complete the operi ation of discharging, andthe lumber or timber will be left upon the ground' in nearly or quite ascompact a condition as that which it occupied while placed upon thewagon. Upon the lower or rear part of the side frames D aforesaid, islikewise placed the rotating rod It with its ends projecting beyond thesides thereof, and upon which are placed the ratchetwheel S, pawl T,lever W, and tightening or binding chain V. Both ends of this chainbeing thrown over the lumber or timber and secured to the ends of thesaid rod lt, as shown, and by means of the lever Wtightly woundthereupon, and thus firmly held by the ratchetwheel S and p awl T itwill serve the important purpose of holding the lumber upon the wagonwhile in transit.

Another important,'essential, and peculiar feature of my invention isthe horizontal curved plateX, or fifth-wheel, as it is technicallycalled, the upper or' concave surface of which is. perfectly smooth, soas' to allow it to rotate easily under the bolster H as the draftanimals deviate from a direct line of progress.

The object sought to be attained by the curved formation of the saidfifth-wheel X Iare two-fold, namely, the elevation of the forward endofthe said side frame D, so as to aly lowing` claims:

` l. The concave plat-e or fth-Wheel X,When

the same is arranged on a Wagon or truck so as to operate substantiallyas described.

2. The lumber or dumping-Wagon, arranged as herein described, having aconcave fthwheel, X, the Whole constructed substantially its shown.
